##Nova控制节点集群
# controller 安装

#########以下在controller1执行
#创建Nova数据库、用户、认证,前面已设置
source ./admin-openstack.sh || { echo "加载前面设置的admin-openstack.sh环境变量脚本";exit; }

# keystone上服务注册 ,创建nova用户、服务、API
# nova用户前面已建

openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1
#创建placement用户、服务、API
openstack user create --domain default --password=placement placement
openstack role add --project service --user placement admin
openstack service create --name placement --description "Placement API" placement
